Quercus agrifolia, the coast live oak, is an evergreen oak (highly variable and often shrubby), native to the California Floristic Province. The fragrant leaves and stems give chaparral its characteristic fragrance. On the far side of the San Gabriel River is the Alamitos Bay Marina. Toyon is a prominent component of the coastal sage scrub plant community, and is a part of drought-adapted chaparral and mixed oak woodland habitats. It’s awfully hard to say no to a payoff like that. They have been observed stealing acorns from woodpecker caches as well as from the caches of other jays they have observed stashing their acorns. A panfish popular with anglers, the green sunfish is also kept as an aquarium fish by hobbyists.

The California ground squirrel (Otospermophilus beecheyi), is a common and easily observed ground squirrel of the western United States and the Baja California Peninsula; it is common in Oregon and California and its range has relatively recently extended into Washington and northwestern Nevada.

The adult acorn woodpecker has a brownish-black head, back, wings and tail, white forehead, throat, belly and rump. Trail access will be on the right. They can be seen during the day, but they are most active in the evening and at night.

California scrub jays, like many other corvids, exploit seasonal food availability by storing food in scattered caches. Turn left on E. Beverly Blvd. View detailed trail descriptions, trail maps, reviews, photos, trail itineraries, directions and more on TrailLink. The tips of the stems, stem attaching the leaf to the stems (petiole), the veins of the leaves, and the edges of the leaves, are a glowing reddish color all year long. Weights vary from about 0.8 to 2.2 pounds (0.36 to 1.00 kg), and length (including tail) from 17 to 24 inches (43 to 61 cm).

The brown pelican (Pelecanus occidentalis) is a small pelican found in the Americas. The main trunk can fork close to the ground, making it look like two trees that have grown together, then diverged.
